noun. Term used to describe over-inflated outer pussy lips. Commonly found on a woman who was really fat at one time, but now she is much thinner. She still has a big fat snapper. When a chick loses weight, the hooters are the first to go, but the snapper usually stays big and fat.
Guy: Dude, you're ho looks great since she lost all that weight.
Friend: Yeah, I know, but she still has a big "pouty" hangin' on her. Look at that big bulge in her shorts.
